The control method and control system of hot water storage tank and hot water storage tank
Technical field
The present invention relates to hot water storage tank technical fields, in particular to the control of a kind of hot water storage tank and hot water storage tank Method further relates to a kind of control system of hot water storage tank.
Background technique
With the development of hot water machine technology, the requirement to hot water storage tank has higher requirement, at present the water tank of hot water machine In addition to provide store hot water function other than, various heating sources can also be connected, height water temperature is provided, but all be need by with the external world This function is realized in combination, round-the-clock can guarantee that stable height water temperature exports without a kind of, while not by the shadow of external heat source Loud water tank.
Therefore, as why not influenced by external environment, temperature condition and heating source situation, it is round-the-clock can guarantee it is automatic defeated High-low-temperature out becomes current urgent problem to be solved.
Summary of the invention
The present invention is directed to solve at least one of the technical problems existing in the prior art or related technologies.
For this purpose, an object of the present invention is to provide a kind of hot water storage tanks.
It is another object of the present invention to propose a kind of control method of hot water storage tank.
Yet another object of the invention is that proposing a kind of control system of hot water storage tank.
In view of this, the invention proposes a kind of hot water storage tanks, comprising: shell is provided with water inlet, water outlet on shell And sewage draining exit；Cavity surrounds cavity by shell, and inside cavity is equipped with water；At least two electric heating tubes are arranged in shell On, extend to inside cavity；At least two temperature sensors are arranged on shell, extend to inside cavity；At least two heating Portion in the cavity is arranged in coil pipe；At least one floor heating heat exchange coil pipe, portion, at least one controller, setting exist in the cavity for setting On the shell.
Hot water storage tank according to the present invention, the principle being layered using hot water in hot water storage tank are rationally designed in water tank at least Two electric heating tubes, at least two heating coils, at least one floor heating heat exchange coil pipe, at least two temperature sensors, guarantee It is not influenced by ambient temperature condition and heating source situation, reaches the requirement of round-the-clock different water temperatures, can both mention For floor heating water at low temperature, and life high-temperature-hot-water can be provided, while helping to improve collecting efficiency, reduce thermal loss, from And reach energy-efficient purpose.
In addition, above-mentioned hot water storage tank according to the present invention, can also have the following additional technical features:
In the above-mentioned technical solutions, it is preferable that the quantity of at least two electric heating tubes is two, respectively the first electric heating Pipe and the second electric heating tube；Wherein, the first electric heating tube is located at the top of shell, and the second electric heating tube is located at the middle part of shell； The quantity of at least two temperature sensors is two, respectively the first temperature sensor and second temperature sensor；Wherein, first Temperature sensor is located at the top of the first electric heating tube, and second temperature sensor is located at the top of the second electric heating tube；At least two The quantity of a heating coil is two, respectively the first heating coil and the second heating coil；Wherein, the first heating coil is located at Cavity middle and lower part, the second heating coil are located at cavity lower part；The quantity of at least one floor heating heat exchange coil pipe is one, floor heating heat exchange Coil pipe is located at cavity middle and upper part, and the quantity of at least one controller is one, and controller is located at shell middle and upper part.
In the technical scheme, the principle being layered using hot water in hot water storage tank is arranged two in the middle and top part of water tank Electric heating tube can heat hot water storage tank and guarantee leaving water temperature, while avoid the water heating to entire water tank, significantly reduce The power of electric heating tube facilitates the service life for extending electric heating tube；In cavity middle and lower part and lower part, two heating dish are set Pipe can connect two external heating sources, match control logic appropriate, be added by two heating coils to the water of water tank Heat, to meet different temperature requirements；One floor heating heat exchange coil pipe is set in cavity middle and upper part, since hot water is layered, in cavity The temperature on top facilitates the demand for being rapidly achieved floor heating water at low temperature；Two temperature sensors are separately positioned on two electric heating tubes Top, perception water tank in the middle part of and top temperature；And then guarantee not by ambient temperature condition and heating source situation It influences, reaches the requirement of round-the-clock different water temperatures, can not only provide floor heating water at low temperature, but also life Gao Wenre can be provided Water, while collecting efficiency is helped to improve, thermal loss is reduced, to reach energy-efficient purpose.
